STUBBLE-BURN ER.

JIPECIFICATION forming part of Letters Patent No. 659,869, dated October 16, 1900.

Application filed February 3, 1900. Serial No. 3,800. (No model.)

To (tu whom, it may concern.-

Beitknown that we, ROBERT IRELAND, AR- THUR LoCKE AsHDowN, and MORRIS SANT- Foun HOLMES, subjects of Her Majesty the Queen of Great Britain, residing at Portage La Prairie, county of Portage La Prairie, Province of Manitoba, Canada, have invented certain new and useful Improvements in Stubble-Burners; and we do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to machin es for burning stubble; and its object is to provide an appara-tus of this character which is simple in construction, effective in operation, and which can be manufactured at a moderate cost.

To these ends the invention consists in an apparatus for burning stubble, duc., constructed substantially as hereinafter illustratcd and described, and defined in the appended claims.

Referring to the drawings, in which similar letters of reference indicate similar parts, Figure l is a viewin perspective of an apparatus for burning stubble constructed in accordance with this invention. Fig. 2 isa plan view thereof. Fig. 3 is a vertical longitudinal section. Fig. 4 is a transverse section on the line -l -LL of Fig. 2, partly broken away to show the construction. Fig. 5 is a view in perspective, partly in section, of one of the burners.

In the drawings, A represents the frame and running-gear of an apparatus for burning stubble constructed in accordance with this invention and which may be of any dimensions best suited for the intended purpose. As shown, the frame is constructed of angleiron and may be suitably braced in order to give the requisite strength.

The frame A is pivotally supported in the lower ends of the levers d, which are rotatably mounted on the axle of the running-gear. The upper ends of the levers extend considerably above the frame and are united by means of a beam A". A suitable lever mechanism A2 is mounted upon the frame A and is connected to the beam A by means of the rod A3. By means of this construction it will be seen that by operating the lever mechanism A2 the main portion of the frame may be raised or lowered when desired.

Upon the front portion of the frame A is mounted a tank or reservoir B for containing the liquid fuel used in burning the stubble. It is proposed to use naphtha for this purpose, though it is obvious that any suitable fuel in fluid form may be substituted, if desired.

A suitable air-pump B is connected With the tank B, whereby the tank may be charged lwith compressed air for the purpose of properly feeding the fuel to the burners. A suitable pressure-gage B2 may be provided, if desi red. Leading from the tank B are the feedpipes b, of which there are'preferably two, though it is obvious that the number may be varied to suit the demands of the apparatus. The feed-pipes l) extend rearwardly over the main portion of the machine and then downwardly and communicate with the transverse pipes b, to each of which is connected a series of burners h2 of any suitable construction adapted tothe use of fluid fuel.

As shown, the burners are constructed of a coiled pipe terminating at its upper eX- tremity in a valved nozzle 53,(see Fig. 5,) which is located in the center of the coil, so as to direct the flame downwardly through the center of the coil onto the stubble beneath each burner. By means of this construction the iiame is protected from drafts by the surrounding coil and the ame heats the coil to a very high temperature, thus volatilizing the iiuid in the Well-known manner common to Huid-burners. l

In front of` the forward row of burners is pivotally mounted a shield D, the lower portionof which is adapted to Contact with the surface of the ground, while the upper portion curves over the top of the burners b2, thereby protecting the flame and coniining it to the proper place. Suitable springs d may be provided, if desired, to keep the shield down on the ground in its operative position, though the weight of the shield Will ordinarily be found sufficient for this purpose.

At a suitable point forward of the burners b2 is a fuel distributing or spraying device D, which consists of the fuel-supply pipe Cl',com municating with the tank B and having a spraying or distributing nozzle d2 at each end of a transverse distributing-pipe (Z3, secured to the lower end of the pipe d'.

The fuel distributing or spraying device is disposed at one side of the burners, in advance thereof, and the nozzles of this fuel distributing: or spraying device are constructed for the free discharge of the liquid fuel upon or over the ground traversed by the machine. This free distribution of the liquid fuel saturates the ground or the vegetable growth thereon which it is desired to destroy, and the fu'el is ignited by the flame from the burners, whereby the growths are thoroughly consumed.

A suitable shield'cl4 is supported on the u frame A and is adapted to properly direct the fluid fuel to the stubble as it is sprayed through the nozzles d2. The purpose of this construction is to thoroughly 'saturate the stubble with the fluid fuel, so that when ignited by the flame from the burners the intense heat will insure the destruction of the stubble, not only consuming the brush but killing the roots. By this means the roughest land can be quickly and easily cleaned of all objectionable roots and Weeds and be brought into suitable condition for sowing or planting.

In the front portion of the main frame and forward of the spraying device D is pivotally mounted the shield D2, which is similar in function and operation to the shield D, eX- cept that it has no upwardly-curved portion, but is preferably a straight metal plate which contacts with the ground and may be supplied with suitable springs d5, as shown in Fig. 3.

The feed-pipes are provided with suitable valves, whereby a portion only of the burners may be used, if desired, and the intensity of the heat regulated to suit the requirements of the ground being treated.

The operation of the apparatus is believed to be obvious in view of the above description and requires no further detailed explanation.

While We have herein shown a preferred form of carrying our invention into effect, yet we do not desire to limit ourselves to such preferred details of construction, but claim the right to use any and all modifications thereof which will serve to carry into effect the objects to be attained `by this invention in so far as such modifications and changes may fall Within the spirit and scope of our said invention.

We claiml. A stubble-burner comprising a frame, burners mounted thereon, a fuel-distributing mechanism also carried by the frame and arranged to freely discharge liquid fuel over the ground traversed by the machine, and means for supplying liquid fuel to said burners and 4to the distributing mechanism, substantially as described.

2. A stubble-burner comprising a frame, burners mounted thereon, a fuel-distributing mechanism carried by the frame adjacent to the burners and arranged to freely discharge liquid fuel over the ground traversed by the machine, and a shield arranged in a plane between the burners and the distributing mechanism, substantially as described.

3. An apparatus for burning stubble, comprising a frame; a reservoir for iiuid fuel mount-ed upon said frame; a plurality of burners carried by said frame; a spraying device arranged on said frame in front of said burners; and feed-pipes connecting said reservoir with said burners and said spraying device, substantially as described.

4. An apparatus-for burning stubble, com- `prising a frame; a reservoir for fluid fuel mounted upon said frame; a plurality of burners carried by said frame; a spraying device mounted upon said frame in front of said burners; feedpipes connecting said burners and said spraying device with the reservoir; and guards pivotally connected to said frame and located in frontof said burners and said spraying device, substantially as described.

5. A stubble-burner comprising suit-able carrying-wheels, vertically-disposed levers hung on said wheels, a frame supported by the lower ends of said levers, a cross-beam connected to upper ends of said levers, burners mounted on the frame and adjustable therewith, an adjusting-lever connected with the cross-beam and adapted to turn the vertically-disposed levers for raising or lowering thev burner-carrying frame, and a reservoir having pipe connections with the burners, substantially as described.

6. A stubble-burner comprising a frame, a fuel-distributing pipe on said frame and provided with the spray-nozzles, a hood over the distributing-pipe, burners arranged iu series and yin rear of the distributing-pipe, and means for supplying liquid fuel to the burn,- ers and the distributing-pipe, substantially as described.

7. A stubbleburner comprising a frame, a yieldable shield D2 thereon, a fuel-dist-ributing device arranged transversely on the frame and in rear of said shield, burners on the rear part of the frame, and another shield hung on the frame in a plane between the liquid-fuel-distributing device and the burners, substantially as described.
